Pakistan cricket officials Saturday termed shifting of their home series against India to neutral venues as "mere speculation", saying preparations are at full swing in their country. India are scheduled to tour Pakistan in January-February to play a side game, three Tests, five one-day internationals and a Twenty20 match but the tour is already in doubt over the security situation in the host country. But PCB's chief operating officer Saleem Altaf voiced confidence the series would go ahead as per the schedule.
